in tho embodiment of an invention as &iscloscii in Vigor-cs 1 to 4 inc osivo of tlie drowiog, l have shown my improvcd clip as being formccl irom a single clon ted strip of flat. or shoot mcioi. The mcto employw should posscso considerable i88iil9m3 in order to function proporly,. yet shoulr also be sufii ciciitly rigid to micro xi forcible and tirm gripggiirig girossurc upon the wirc or buss bar who 1 it origo or.

The strip 1mm, is folded upon itself, as at 1, so tlmt it is ilivklcd into o pair of arms 2 and 3, which normaly tend to spring apart for room distance by rcoson of illt? rcsilicncy in the mctol. The arms 2 and 3 are provided with cnlorgcd frco ends as at 4 and 5, and openings Q oro tiicrcio provided to permit the massage of a, binding post 7 or other similar projcctim port on an clectrical instrument, a port 0 which is indicated at 8.

Tim arm 3 is provided with a pair of later ally oxtoiioiing win s 9, which are tormcfi on the longitudinal si e cd es of the arm at a position odjoceot to the fiend or told I in tho otripo Tlicso wings 9 are folded so that they lic oi oulistontiolly ri ht angles to the piano of tire owns 2 owl 3 am they tlius project owoy from tho orm 3 and toward the arm 2.

From the foregoing it will be readily in pororit how my improved clip, just obove scribocl, operates. It is shown in Figure 1 iii dotted lines in the form in which it a pears when it is first slip over the bin mg post T. A wire or uss bar 10 is incertcd botwoon the inner face of the fold l of the clip and the side oclgos 11 of the wings 9, said side edges 11 being those which are located nearest to the told 11. The binding post nut 12 is then threaded down firmly, with the result that the wings Stare inclined torwardly, and they firmly grip the wire between their forward edges 11 and the inner face of the strip at the fold 1. llhe grip exerted on the wire is a firm and strong one regardless of whether the wire is of the type known as buss bar or whether it is of the stranded type, and a clean, strong and effective mechanical and electrical joint is the result.

In Figures 5 and 6 is shown a modification of my improved clip, wherein a single gripping wing or lug 13 is utilized to hold the wire 10 between its forward edge 14 and the fold 1 in the strip. l his wing 13 is struck out of the body of the arm 3 and is bent toward the arm 2 which is provided with an aperture 15 through which the wing 13 may project when the arms 2 and 3 are compressed toward one another.

In the modification of my invention disclosed in Figures 7 to 9 inclusive, the clip is in the main, similar to that disclosed in Figures 1 to 4 inclusive, except that its gripping members or wings, which are shown at 17 and 18, are made wider than those disclosed at 9 in Figures 1 to 4, so that they grip the wire or buss bar 10 between their notched lower edges 19 and the upper face 20 of the arm 2. Figure 8 clearly discloses the positions of the various parts of the clip when the same is in its final position. A feature of the clip disclosed at Figures 7., 8 and 9 is that it may confine and hold at least two wires. Une of the wires so held and confined may be gripped as shown, that is. between the notched or recessed ends 19 of the wings 17 and the face of the part 20, and a second wire may be simultaneously gripped and held between the front edges of said wings and the looped or folded part 1 as is done in the embodiment of my invention disclosed in Figures 1 to t inclusive.

In the modification of my device disclosed in Figures 10 and 11., the clip is provided with an aperture 21, located on the line of meagre the :t'old,and a wire or buss bar 10 may be inserted from the front of the clip through the aperture 21 so that it passes between struck-up prongs 22 and23. The prongs 22 are shown as being struck from the body of the arm 2 and the prong 23 is formed from the body of the arm 3. These prongs 22 and 23 have their lower edges notched as at 2 1, so that when the arms-2 and 3 are compressed towards one another by the action of the nut 12 on the bindin post, the lower edges 2% on the prongs will rmly grip and hold the buss bar or wire. I

From the foregoing it will be apparent that l have produced an electrical connection clip of extreme simplicity of construction, yet one which will be highly efficient in operation. A feature ofimportance is that the nature of the clip enables it to act as a lock washer,

for the binding post nut, for the normal tendency of the arms 2 and 3 to spring apart causes them to exert spring pressure against the nut tending to cause it to remain firmly in position under all conditions of use.

Having described several embodiments of my invention, it is obvious that the same is not to be restricted --thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.

What 1 claim is 1. An article of the class described comprising a strip folded upon itself, wings bent from said strip and positioned no further away from the fold than the normal distance between the toldedparts of the strip, said wings being adapted to gripa wire between one of their edges and fold in the said strip.

2. An article of the class described comprising a strip folded upon itself to form a pair of flexible arms capable of movement toward one another, a wing bent from one or said arms and located sufficiently close to the fold in the strip to cause a cylindrical-wire to be firmly gripped between that edge of the wing which is located nearest to the fold and the fold, when the arms are compressed toward one another.
